To all whom, t may concern,.-

Be. it known that I, FREDERICK G. WISE- LOGEI., a. citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements inEvaporators and Extractors for Garbage Reduction, of which the followingis a specification.

The object of my invention is to produce xo an, apparatus for receivinggarbage and extracting therefrom the fats and oils, at the same timedrying the material.

The accompanying drawings illustrate my invention:

15 Figure 1 is a longitudinal vertical section;

ig. 2 an elevation; Fig. 3 a transverse section, and Fig. 4 a transversesectional detail of the removable filter diaphragm.

Inl the drawings, indicates a cylindrical` 2o or substantiallycylindrical structure closed at its ends by heads 11 and 12, each ofsaidand perforated plates 17 heads having a central bearing in which isjournaled a shaft 13 provided with stirring blades 14 which traverse thechamber or main 2 5 body closely adjacent the bottom. The main body 10is preferably formed of a pair of mating bottom castings 10-10, and asingle saddle casting 10. The two castings 10 are so formed at theiradjacent edges as 3o to form a longitudinal channel 15 which isdepressed below the main line of the walls of the cylinder and formed ineach vertical edge of the channel is a longitudinal groove 16 ada ted toreceive the opposite edges of a 3 5 perfIOrated plate 17 which extendsthe entire length of the chamber. Plate 17 carries above it a perforatedplate 18, preferably having finer perforations and being spaced fromplatel' by suitable thimbles 19 and 4c bolts 20. Laid between plates 17and 18 is a filter mat 21, formed conveniently of burlap or othersimilar fabric. The upper plate 18 of the filter-lies substantially inline with, and as a continuation of, the inner faces of the 45 castings10. In order to facilitate the removal and replacement of the filterstructure I provide the head 11 with a door 25 which may be swung so asto open the entire space at the end of channel and thus permit 50 plate17, with its attached parts, to be withdrawn longitudinally from thestructure. Castings 10 and 10 are thicker at their adjacent edges thanat intermediat points and a sheet jacket 26 is bridged over the spacci 55 between the thickened edges, thus forming at i the bottom of thecylinder a pair of steam jackets 27-27 and at the topa water j acket 28,steam pipes 29 leading into jackets 27 and suitable water circulatingpipes 30 leading into and out of the water jacket 2S. 6o Suitable pipesgive ac cess to'the interior of the cylinder at the top thereof and apipe 36 leads from the channel 15.

. n operation the garbage is introduced through pipes 35 and asufficient quantity of 65 alcohol or benzin introduced. Pipes 35 arethen closed and the chamber is heated by steam within jackets 27. Shaft13 is then rotated and the garbage thoroughly heated, the gases passingOH through an outlet 40 7o while the grease and oils settIe to thebottom chamber and pass through the filter mat 21 and 18 through channel15, from whence they may iiow through pipe 36. be retarded by a suitablevalve (not shown) in a continuation of the ipe 40. As the cookingproceeds the volatile alcohol or benzin rises to the top of the chamberwhere, coming in contact with the cooling saddle, it 8o is condensed andreturned to the mass.

en the material has been thoroughh7 dried and all the oils and greaseextracted the dried material maybe discharged through the opening closedby door 25 by rotation of 85 the stirrer. When it is desired to renewthe filter mat the filter structure may be readily withdrawnlongitudinally through the same opening and a new mat placed therein.

I claim as my invention z 9o In an extractor and evaporator, thecombination with a receiving chamber having a longitudinal slot in itsbottom and an opening in its head at the end of said slot, a closure forsaid opening, and a lr structure supported in said channel andlongitudinally withdrawable therefrom through the opening in the head, aheatingjaket embracing the lower side of the receiving chamber and acooling saddle embracing the up- Ioc per side of saidchamber. v"

n witness whereof, I, have hereunto set my hand and seal atIndianapolis, Indiana, this 3rd day of October, A. D. one thousand ninehundred and six.
